HENRY BRUNN, OF BUFFALO, NEW YORK.

CARRIAG E-PO LE.

SPECIFICATION forming part of Letters Patent No. 634,550, dated October 10, 1899.

Application led July 31,1899. Serial No. 725 ,619. (No model.)

To all wtont it may concern:

Be it known that I, HENRY BEUNN, a citizen of the United States, residing at Bualo, in the county of Erie and State of New York, have invented new and useful Improvements in Carriage-Poles, of which the following is a specification.

This invention relates to a tip which is secured to the rear end of a carriage-pole and inserted in the pole-socket.

The object of my invention is to construct this tip in such manner that it can be snugly fitted in the socket, so that the rear end of the pole is held steadily in the socket and rattling and Wear of the parts are prevented.

In the accompanying drawings, Figure l is a longitudinal section of the rear end of a carriage-pole provided with my improved tip and inserted in the pole-socket. Fig. 2 is a side elevation of the rear end of the'carriage-pole and tip. Fig. 3 is a cross-section in line 3v 3, Fig. l.

Like letters of reference refer to like parts in the several figures. i

A represents the rear end of a carriage-pole, and B the pole-socket, which is secu red to the carriage or other vehicle and which supports the rear end of the pole. This socket may be of any 'suitable or Well-known construction and secured to the carriage in any suitable manner.

The rear end of the poleis provided with a metallic tip C, extending rearwardly from the pole and carrying a yielding or expansible head D. The tip C is provided in its front side with a socket c, which receives the rear end of the pole, and in its rear side with a socket d, which receivesthe front portion of the head D. The latter is made of yielding rubber or other suitable material and provided with a central longitudinal opening e, which permits the head to be applied to a screw-bolt F, pr0jecting rearwardly from the body or partition g of the tip D. This screwbolt and bear-against the'rear end of the head D. The latter is of straight cylindrical form in its normal condition. By tightening the screw-nut the head is compressed longitudinallyand bulged out in rear of the tip until it projects beyond the peripheral face of the rear portion of the tip. The latter is somewhat smaller in diameter than the internal diameter of the socket. For fitting the tip to the socket the expansible or yielding head is compressed until'its bulging part has become so large in diameter that it ts snugly in the socket, as represented in Fig. l.l When the tip is now inserted into the socket, the yielding head alone comes in Contact with the socket, while the adjacent metallic part of the tip being smaller in diameter than the socket is kept out of contact with the latter. The pole is by this means tightly held in the socket,I thereby avoiding rattling and the wear which results from looseness of the parts.

When the bulging part of the fiexible' head has become compressed by longcontinued use, it can )be readily expanded to again closely tit the socket by tightening the nut on the screw-bolt.

I claim as my invention*- 1. The combination with a carriage-pole, of a yielding head secured to the rear end of the pole and adapted to be inserted into the polesocket, said head having its outer surface projecting beyond the adjacent portion of the pole and holding the same out of contact with the socket, substantially as set forth.

y 2. A carriage-pole provided at its rear end with al tip having a yielding head and means whereby said head can be expanded to it the pole-socket, substantially as set forth.

3. A carriage-pole provided at its rear end v with ati p provid ed with a screw-bolt projecting rearwardly from said tip, a yielding head arranged upon said bolt, and a screw-nut applied to said bolt and bearing against the rear end of said head for compressing and expand- HENRY BRUNN.
